acceptable macronutrient distribution range (AMDR) The range of intake for a macronutrient that is associated with decreased risk of chronic disease while providing sufficient intake of essential nutrients.

aerobic respiration The 10-step metabolic process of breaking glucose down to intermediate pyruvate, which is converted to acetyl-coA and enters the citric acid cycle. Occurs in the mitochondria and cytoplasm in the presence of oxygen; produces a net 36 ATP.

air displacement plethysmography (ADP) (brand name is BodPod) A device that uses the displacement of air to measure body volume and density; compare to hydrostatic weighing which uses the displacement of water to estimate body composition.

alanine-glucose cycle The cycle of transporting pyruvate and nitrogen from the muscle tissues to the liver as the amino acid alanine. In the liver, the alanine unloads the nitrogen group to become pyruvate, which is converted to glucose through gluconeogenesis. This process moves the work of gluconeogenesis from the muscle to the liver.

aldosterone A hormone released by the adrenal gland that helps to maintain normal blood sodium levels by increasing the kidney's reabsorption of sodium and decreasing the amount of sodium lost in sweat.
